Wengang Zhai, Wei Zhou, Zhiguang Zhu, Mui Ling Sharon Nai
Abstract
In article 2100664, Zhou, Nai, and co-workers show that 304L and 316L have similar compositions. However, a selective laser melted 304L and 316L show a significant difference in grain size and morphology. Their microstructures and mechanical properties are compared using a scanning electron microscope, electron backscattered diffraction, nanohardness, and tensile tests. This comparative study proposes a method for grain refinement and microstructure tuning in additive manufacturing.
